CLEANING-MACHINE No. 890,405.v

To all 'whom 'it may concern:

Be it known that I, ROBERT C. CLARK, a

citizen of the United States ofAmerica, re.

siding at Tacoma, in the county of .lPierce and State of Washington, have invented certain new and useful Im rovements in Cleanin -Machines, of which t e following is a spec' cation, reference being had therein to the accompanying drawing.

This invention relates to devices for brush- 'ing arnd cleaning articles,- Vand has for its object to provide a mechanism whereby the articles may be cleaned without any handling I attain this ob ect by the mechanism and devices illustrated in 'the accompanying drawing, in` which Figure 1 is a side elevation of my invention, a part of the shield being broken away to reveal the scouring or brushing mechan ism.. Fig. 2 is a vertical cross section of the operating motor, and Fig. 3 is a plan thereof;

Similar numerals of reference refer to similar ,Iplarts throughout the several views.

is invention consists in a water or air motor which drives a rotating brush,- sponge, or other scouring means, and in which the -waste air or water therefrom is conducted 'and sprayed around said rotated brush. A

sliding shield is mounted thereon and surrounds said rotated brush .and the sprayerand prevents the splashing of the water or scattering of the dust from the cleansed article, said shield being elevated from the bottom to allow the air orwater and the impurities carried thereby to ass away. 1

The handle 1 is secure to the center of the upper motor casing 2, the lower casing 3 being secured to said casing 2 by means of screws or other ordinary device, said casings 2 and 3 forming between them the round compartment in which the wheel 4 rotates'. This wheel 4 is provided with a series of cavities cut in its outer edge, as illustrated in Fig. 3, and forming vanes adapted to receive the impact of the air or water and to transform the same into rotary motion. The said wheel 4 is mounted on a vertical axis having an upper boss 5 extending upward into a hole in the up er casing 2, and a lower boss 6 ex? Specification of Letters Patent.

Application led September 3, 1907.

'and so that the shield will cover it.

hole in the center of the bridge 7 and ltransmits the rotary motion of the wheel 4 to the brush or sponge which is secured to its other end. The air or water is conducted through a suitable flexible hose 9 to the passage ,10 formed in the side of the casing 2, said passage 10 leading to the inside of said casing at practically a tangent to the rotating wheel 4 so that the flow ofthe Huid in said passage 10 will strikethe vanes formed on the wheel 4 at a sufficient angle and will cause them to rotate. The cavity formed in the casings 2 and 3 is such as to allow plenty of room'for the air or water to do its work on the wheel and then iiow away around the arms o'f the bridge 7. The large pipe 11 is screwed into the lower casing 3 and surrounds the shaft 8 and carries away the air or water from the motor. The pipe 11 has a cap 12 screwed to its lower end, said cap having a number of spray holes 13 around its lower end, through which the air or water from the motor is sprayed on to the article being cleansed and on to the back of the rotating scouring brush. The bottom of the shaft 8 passes through the cap 12 and is screwed into the removable frame 1 4 which carries the brush, sponge or other similar scouring means, said frame being properly shaped so that the brush will clean the article. A light shield 15 is mounted on the pipe 11 and is perfectly free to move thereon, said shield being shaped so as to inclose the article being cleaned above it and all sides thereof, and being provided with suitable legs 16 so that it will be slightly elevated to allow the escape of the impurities from this machine.

When Water is used the vessel to be cleaned is usually placed in a sink and the machine is placed so that the brush will enter the vesshel T e pipe 9 is then attached to the faucet and the water turned on, causing the motor and with it the brush, to rotate rapidly and scour the sides and bottom of the vessel at the same time that the waste water from the motor floods the vessel and carries away all the impurities. l/Vhen the machine is used for cleaning Windows or railway coach sides or carriages or other polished surfaces, a sponge is used with water. Then the upholstery of a room, railway car, etc., is to be cleaned, a' suitable brush is used with air as the propelling force, the shape of the brush a scouring means secured to the end of said rotating, shaft; a Waste pipe secured to said frame and surrounding said shatt, and eX- tending from the frame to the scouring means, and adapted to convey the fluid from the motor to and around the scouring means; a spraying attachment secured to said Waste pipe, and adapted to spray the fluid ,on the 'rotating scouring means; and a protective shield loosely mounted on theWaste pipe and surrounding the scouring means, substantially as and for the purpose specified,

In testimony whereof I aiiix my signature in presence of two Witnesses.

ROBERT C. CLARK.
